“Angiosarcoma is an aggressive cancer with limited therapeutic options, and we are excited to begin this randomized Phase 3 clinical trial of TRC105 as a potential therapy for patients with this disease,” said
About the Phase 3 TAPPAS Study
TRACON is conducting the Phase 3 TAPPAS trial (a randomized Phase 3 trial of TRC105 And Pazopanib versus Pazopanib alone in patients with advanced AngioSarcoma) under Special Protocol Assessment (SPA) with the
Further details of the study are available on www.clinicaltrials.gov under NCT02979899.
TRC105 is a novel, clinical stage antibody to endoglin, a protein overexpressed on proliferating endothelial cells that is essential for angiogenesis, the process of new blood vessel formation. TRC105 is currently being studied in multiple Phase 2 clinical trials sponsored by TRACON or the
Angiosarcoma is an aggressive form of soft tissue sarcoma (STS) of endothelial cell origin that is associated with poor prognosis. Angiosarcoma has a 5-year survival rate of less than 12%, which highlights the aggressive nature of this tumor when compared to a 5-year survival rate of approximately 56% for all STS. Angiosarcoma can arise in any soft tissue structure. About half of patients present with a primary cutaneous lesion. Although resection with curative intent followed by adjuvant radiotherapy is the treatment of choice for localized disease amenable to surgery, approximately 50% of these patients will develop metastases and die from the disease. Furthermore, metastases are frequently present at diagnosis, and resection of metastases is rarely feasible.
Angiosarcoma is an extremely rare disease and meets the definition for an orphan disease in the U.S. and EU, the two regions in which the Phase 3 TAPPAS study is being conducted. The annual incidence of angiosarcoma in the U.S. was reported by the NCI in 2015 to be 475 cases. In the EU the incidence of angiosarcoma is 0.01 per 10,000, accounting for an estimated 508 cases annually.
TRACON develops targeted therapies for cancer, ophthalmic and fibrotic diseases. The Company’s clinical-stage pipeline includes: TRC105, an endoglin antibody that is being developed for the treatment of multiple cancers; DE-122, the ophthalmic formulation of TRC105 that is being developed in wet AMD through a collaboration with

Such statements include, but are not limited to, statements regarding the potential benefits that may be derived from the SPA, the design of the Phase 3 TAPPAS trial and TRC105, TRACON's plans to further develop its product candidates and expectations regarding the initiation, design and timing of future clinical trials by TRACON or third parties. Risks that could cause actual results to differ from those expressed in these forward‐looking statements include: risks associated with clinical development; whether TRACON or others will be able to complete or initiate clinical trials on TRACON’s expected timelines, if at all; whether TRACON will realize expected benefits from the SPA or the design of the Phase 3 TAPPAS trial; the fact that the SPA does not guarantee regulatory approval, even if the Phase 3 trial meets the agreed-upon endpoints; the fact that future preclinical studies and clinical trials may not be successful or otherwise consistent with results from prior studies; potential changes in regulatory requirements in
